Who among the following Chola kings encouraged the Sailendra ruler of Srivijaya to build a Buddhist Vihara in Nagapattinam?

During the reign of Rajaraja I (985–1014 CE), the Chola dynasty maintained cordial relations with the Srivijaya Empire of Southeast Asia [1]. In 1006 CE, the Srivijayan King Mara-vijayottungga-varman, belonging to the Sailendra dynasty, constructed a Buddhist temple in the port town of Nagapattinam [2]. This vihara was named the Chudamani Vihara (or Soolamani-varma-vihara) in honor of the king's father [2]. Rajaraja I encouraged this construction and granted the village of Anaimangalam for the maintenance of the monastery, as recorded in the Larger Leiden Plates [2]. While his successor Rajendra I later launched naval expeditions against Srivijaya due to deteriorating relations, the initial period under Rajaraja I was marked by diplomatic and religious cooperation, facilitating the expansion of Tamil merchant associations into Southeast Asia [1].
